. What is the goal of an experimental study?

A researcher theorizes that people are likely to perspire more when telling
embarrassing stories than when telling funny stories. Volunteers are asked to
record a memory of an embarrassing or a funny incident and their perspiration is
measured. On some days, but not others, the lab where the recordings are done is
very hot. Based on this information, the researcher should be concerned most
about

In the context of conducting psychological research, systematic control
procedures are intended to

A psychologist is doing research for a pharmaceutical company. The drugs he is
testing are numbered so that he does not know what they are, nor does he know
which participants are receiving which drugs. His participants are not aware of the
types of drugs they take. The systematic control that is being used in this study is
called a

Why do we need random assignment of subjects to the Experimental and Control
groups?

Since we normally cannot have access to the full population of interest,
researchers are faced with taking a representative sample of the population.
Which of the following is NOT true of a representative sample?

A representative sample must include members of different age groups,
even when the target population is of children.

What does a strongest correlation coefficient indicate? Explain it using your
example.

What does a positive correlation mean? Explain it using your example

What does a negative correlation mean? Explain it using your example

After you present your excuse for missing class, your professor tells you that she
has found that the more classes students miss, the lower their test grades tend to
be. This relationship illustrates a(n)

When there is no relationship between two variables, what is the correlation
coefficient?

Does correlational method allow us to make predictions about one variable based
on information from another variable?

In company A, the relationship between motivation and worker productivity is
+0.60, while in company B, the relationship between motivation and worker productivity is -0.90. Based upon this knowledge, which of the following
observations is true?

The capacity to accurately predict worker productivity from worker
motivation is greater in company B.

Suppose that the relationship between the number of asking questions in the class
and the test score is +0.75 in Biology, and -0.15 in Philosophy.

a. a positive correlation. The more questions a student asks in the class, the
higher score the student gets in a test.
b. a negative correlation. The more questions a student asks in the class, the
lower score the student gets in a test.
c. strong
d. weak
e. biology

. Are researchers obligated to respect the basic rights of research participants? If so,
how is this ensured?

Question above, what do you call the special committee?

What is "informed consent"?

The process in which an investigator gives information about the research and
explain possible risks and benefits that may occur to a participant in the study and
the participant signs a form indicating his/her willingness of participation.
Informed consent should be conducted before the study.

When we make assumptions about the causes of behavior, collect and analyze data,
and support or refute our findings based on empirical evidence, we are conducting
__________.

A ______________ is a set of related assumptions from which testable predictions can
be generated. .

One ________________ would be that older adults are better drivers than are young
adults. Thus, a _________________ would be that drivers age 40 and older have fewer
traffic accidents than do drivers age 16 to 39.

A trait, characteristic, or value that changes between or within people, places, objects,
or conditions is a __________.

Jessica wants to conduct a study about differences in jealousy between men and
women. She asks 400 college men and women a series of questions about hypothetical
scenarios of partner infidelity. What is Jessica's population?

Jessica wants to conduct a study about differences in jealousy between men and
women. She asks 400 college men and women a series of questions about hypothetical
scenarios of partner infidelity. Which of the following is the most probable reason
Jessica's study may be flawed?

Her sample's attitudes may not truly represent the population's attitudes.

A representative sample is a __________.

Which of the following is an important mantra of psychologists with respect to
correlational studies?

a. Correlation does not indicate causation.
b. Correlational studies will use more laboratory resources.
c. Correlational data are much more difficult to analyze than other data.
d. None of these. -----------------------

Why is it important for researchers to use a control group in a scientific study?

. Jaleel is a participant in a cognitive experiment, but he does not know if he is in the
experimental group or the control group. The researchers, however, are aware of the
condition to which he has been assigned. The study in which Jaleel is participating is
called __________.

The arithmetic average of a series of numbers is called the __________.

A class's mean score on the midterm exam was 78.2, and the standard deviation was
15.8. The class's mean score on the final exam was 81.3, with a standard deviation of 4.5.
From these statistical data, one can interpret which of the following?

There was more variability in the scores on the midterm exam than on the final
exam.
